Patented June 16, 1931 REM: (maven, or BASE-L, SWITZERLAND LOADING- OF SILK, OR SILK-CONTAINING TEXTILE MATERIAL Application filed. July 9, 1928, Serial No. 291,292, and in Switzerland August 23, 1927.

The present invention relates to an apparatus for loading natural or artificial silk textile material, or textile material containing natural or artificial silk of suitable type, 5,for example in the form of yarn, hanks or skeins or runs, or in the form of fabrics, in which the textile material can be sufliciently loaded without trouble in the shortest period in a continuous process without interruption by washing, acidification, or neutralization between the separate working stages.

The loading of natural silk, or natural silk-containing material, without washing, acidification, or neutralization of the textile material coming from one loading bath before transference into the succeeding loading bath, which is disadvantageous from both the manufacturing and economical points of view, has first been rendered possible by the knowledge that this troublesome intermediate treatment of the textile material can be dispensed with, if the treatment of the textile material with the solution of metallic stannic chloride, is carried out in the presence of acids or acid salts which either act on the textile material before treatment with the metallic salt, or are added to the solution of the metallic salt.

It has only been possible to load artificial silk I or products containing artificial silk more particularly, without any troublesome technical objections, after the above knowledge had been acquired. The present invention consists of a cham ber provided with closure means and containing one or more supports or carriers for the textile material, the 10 er portion of this chamber being construe as a receptacle for the loading liquid and being connected up with a pipe system having a feed mechanism which allows of circulation of the loading liquid, charging of the receptacle with the loading liquid, and discharge, the loading liquid being returned if necessary to the supply vessel. 1

It is advisable to use horizontal stationary or rotating hollow supports for the textile material to be loaded, which supports are provided with fine apertures on then periphsalt required for the loading, for example pipe system for circulating the loading liq V uid, whereby all the pipes, and the chamber can easily be washed out. 7

The invention is more particularly described by way of example with reference to the accompanying drawings in which Figure l is a side elevation and Figure 2 isa partial plan view of the improved apparatus. r

A suitable number of hollow supporting members having apertures in the walls, for

example cylindrical pipes 3 with a plurality of apertures in the top portion, are arranged horizontally in a tank or vessel l which is adapted to be closed by means of a door and the lower portion of which is constructed as a reservoir 2. A pipe 4 leads from a number of vessels A, B, C, and D, containing the separate loading liquids, into the reservoir 2. Valves 5 are adapted to supply loading liquids from the vessels A, B, C andD separately or together to the reservoir 2 in suitable sequence. The reservoir is provided with two outlet pipes 6 and 7 with valves 8 and 9. The outlet pipe 6 with the valve 8 allows of. running the liquid out of the apparatus, whilst the outlet pipe 7 and valve 9 is connected with a centrifugal pump 10.

This pump 10 feeds the liquid coming I from the reservoir 2 through a pipe 11, and thence either through avalve 13 according to the position through a-pipe 15 and into the supporting members 3, which can if necessary be rotated b means of a mechanism 14, and are provide with outlet apertures for the liquid, or through a valve 12, pipe 16 and one of a number of valves 17a, 17 b, 17 0, 17d, into the corresponding vessels A, B, G and D.

A water pipe 18 and valve 19 are adapted both to wash the supporting members 3 with water through the pipes 11 and 15, and also to clean out the reservoir 2. The water is then led away through the outlet pipe 6.

A vacuum pump (not shown) is connected by means of a pipe 20 and valve 21 with the supporting members 3, and is adapted to remove the excess liquid from the textile igiaterial located on the supporting .mem-

ers 3.

, a The operation of this apparatus 18 for example as follows.

The textile material to be loaded is suspended on the supporting members 3; the chamber 1 is closed and the valve 5 of the vessel A, which contains the pretreatment liquid, for example formic acid, and also the flow valve 22 are opened until suiiicient liqaid has flowed into the reservoir 2. On opening the valve 9 the acid flows to the centrifugal pump, which is in operation and on closmg the valve 12 and opening the valve 13 is pumped by it through the pipes 11 and 15 into the supporting members 3, which are also rotating if necessary, flows through the apertures therein, saturates the textile material and flows down the latter to collect in the reservoir 2 again. After treatment lasting several minutesthe acid under certain circumstances makes one circuit through the reservoir 2, pump 10 and supporting member 3the liquid is returned to the vessel A throu h pipes 11 and 16 by closing the valve 13 and opening the valves 12 and 17A.

The contents of the vessel B are then brought into circulation in similar manner, in order to treat the material with the loading agent, for example a solution of stannic chloride contained in the vessel B, for about five minutes. The extractor can now be brought into. operation on closing the valve 13 and opening the valves 21 and 24 whereby on intermittent operation of the vacuum pump and simultaneous rotation of the supporting members by means of the rotational mechanism 1 1 the excess liquid is gradually removed from the textile material whichat the same time comes in contact with the air,

before the further treatment.

' An extractor adjustable according to the amount of the material, arranged at points other than the point of suspension of the goods, may also be provided instead of the extractor operating through the supporting tubes. a

The material is then saturated in the same manner with the fixing solution, for example a phosphate solution contained in the vessel C and after circulation for about six minutes, this liquid is returned to the vessel C. The valves 12 and 176 are then closed and the apparatus is thoroughly tional loading liquid, for example sodiuinsilicate solution present in the vessel D, and after pumping the excess liquid back into the vessel D, is washed out with water by opening the valves 19 and 8 after closing the valves 12 and 17, whereon the material fully loaded is dried.

. Instead of the liquid being supplied through the supporting members provided with outlet apertures, it can also be supplied for example by being sprayed externally through special devices on to the material laid or suspended on supporting members.

Considerable advantages both as regards the quality of loaded material and also the duration and saving in material are obtained by treatment of the silk-containing textile material in a single apparatus, without removing the material and without any washing, acidification and neutralization between the separate treatments.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:
